This timer draws 7 minutes as 20 concentric rings; one empties every 21 seconds, so a glance shows how far along you are without reading a digit. It chimes at zero, keeps counting in a background tab, runs fullscreen, and exports as a free MP4 video. Handy for the seven-minute workout, microwaving a baked potato, or a lightning talk rehearsal.
Seven minutes is best known for the workout that carries its name, and quietly useful for a soft-set boiled egg and a microwaved potato. The dial drops a ring every twenty-one seconds, which is slow enough to read from across a kitchen and fast enough to see moving between exercises.
The circuit that popularised the name is twelve bodyweight exercises done for thirty seconds each, with ten seconds of rest between them. The arithmetic is worth doing once. Twelve exercises at thirty seconds is six minutes of work; add eleven ten-second rests between them and the total is seven minutes fifty seconds, or eight minutes if you rest after the last move too. So the workout is really an eight minute block, and the 8 minute dial holds it whole. Set this seven minute dial only if you skip the rests, or run the circuit with a chime at each change on an interval page instead.
Seven minutes in boiling water sets the white firmly and leaves the yolk soft at the centre without running: the egg most people mean by soft-boiled. The boiled egg page is this same seven minutes with notes on softer and harder. Start the dial as the egg goes in and lift it at the chime.
A medium potato, pricked all over, takes about seven minutes on high, turned once at the halfway mark. Ring ten is halfway, so turn it when the outer half of the face has gone. Larger potatoes need a couple of minutes more; check with a fork at the chime and restart for two if it resists.
Seven minutes is a common slot at student conferences and internal demos. Rehearse against the dial with the slides open, and if the chime lands before the last slide, the talk is too long, not the clock.
A jammy egg is six minutes; a hard one and the full circuit are eight. There is a seven-minute video on the card, and the timers page lists everything else.
21 seconds. The dial always has 20 rings, and this timer runs 7 minutes.
Yes. The nearest pages are the 6 minute timer and the 8 minute timer, and the custom field on any dial takes an exact length.
Add it as a browser source in OBS; the background stays transparent. Change t for any length.
A radial timer is a free online countdown timer you set in one click: pick a length, press Start, and an alarm sounds at zero. Run several timers at once, take one fullscreen, or pop one out picture-in-picture to float over other apps. Every timer keeps counting in a background tab, and any timer exports as a video. No download, no sign-up.
Its dial draws the countdown as 20 concentric rings, one for each twentieth of the duration. Rings empty one by one, outermost first, so a glance shows how far along you are without reading a digit.
Yes. The countdown follows the clock, so it stays on time while you work in another tab and still chimes at zero. The picture-in-picture popout keeps a small dial in view the whole way.
Yes. Any timer exports as an MP4 or a transparent WebM of the whole countdown, up to 4K and 60 fps, in 16:9, vertical, or square.
Yes. In OBS, add a browser source pointing at radialtimers.com/overlay?t=25m and a transparent dial counts down over your scene. Change t for any length, like 90s or 3h.
As many as you need. Each timer gets its own dial and runs on its own, which suits interval workouts, several dishes on the stove, or a room of activity stations.
